The line graph on the left is a plot of values along the x-axis, which is through the "flattened" minor zones. The surface plot on the right shows values of ψ7fxz2 on a slice drawn through the xz plane (y = 0). The red zone at centre left and the blue zone at centre right are the "flattened" more minor zones evident here. The x-direction is the same for both plots.

The 7fxz2 and 7fxz2 orbitals are identical in appearance and differ only in direction. One can be mapped to the other by a 90° rotation about the z-axis. This is best seen when viewing both together.
